BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a cutting machine, and moreparticularly to a cutting machine for easily and quickly cutting papersheets or gold foils or the like into smaller cut chips, and forautomatically collecting the cut chips.

2. Description of the Prior Art

Typical cutting machines comprise a base having a fixed cutter edge orblade formed or provided therein, and a movable cutter blade pivotallyattached or coupled to the base, and rotatable relative to the base, andmovable toward and away from the fixed cutter edge or blade for cuttingor trimming paper sheets.

Normally, the typical cutting machines may be used to cut or trim papersheets into longitudinal paper straps or strips only, but may not easilycut or trim paper sheets into square, or rectangular, or triangular orhexagonal paper cut chips.

For allowing the paper sheets to be cut or trimmed into square, orrectangular, or triangular or hexagonal paper cut chips, thelongitudinal paper straps or strips should further be cut or trimmed bythe typical cutting machines again, to cut the longitudinal paper strapsor strips in a direction perpendicular to the longitudinal paper, inorder to form the smaller square, or rectangular, or triangular orhexagonal paper cut chips.

However, it is time consuming and it takes a lot of labor work and itwill be difficult to cut paper sheets into the smaller square, orrectangular, or triangular or hexagonal paper cut chips.
